The WMI object contained an invalid value in property BIOSNumLock
Not an error I’ve come across before, but trying to start up a Configuration Manager VM I’ve not used in a while, Hyper-V Manager stated “The WMI object contained an invalid value in property BIOSNumLock” and that the machine was in in “saved-state-critical”.
Opening up the properties of the machine and selecting then deselecting the Num Lock option in the BIOS configuration made this go away.
Very odd.
This sounds like a problem with your pRAM.
I always find that tweaking your pRAM will fix the problem.
